One, hopefully, final question; I am getting a single metal density DRC error flagged at the end of the "Tapeout" job for the CI 2311 Efabless shuttle. I believe this to probably be erroneous considering that neither the precheck nor the openlane flow flagged a DRC error. Is it possible to get a staff override to submit the project anyway and risk it? The applicable files are klayout_met_density.log

Particularly it seems the max density is set to 0.65 and the recorded density is 0.65035 so I don't think it would cause any errors

@jeffdi Can we override the precheck for this submission?
@Christian Duffee what project is this?

I also emailed Nathan Pier about it and he said he'd look into it

I checked the gds file and it looks like everything generated fine
